There is an ongoing debate as to which class of license provides the greater degree que es copyleft freedom. This debate hinges on complex issues such as the definition que es copyleft freedom and whose freedoms are more important, or whether to maximize the freedom of all potential future recipients of a work freedom from the creation of proprietary software.

Non-copyleft free software licenses maximize the freedom of the initial recipient freedom to create proprietary software. In common with the Creative Commons share-alike licensing system, GNU's Free Documentation License allows authors to apply limitations to certain sections of their work, exempting some parts of their creation from the full copyleft mechanism.

In the case of the GFDL, these limitations include the use of invariant sections, which may not be que es copyleft by future editors. The initial intention of the GFDL was as a device for supporting the documentation of copylefted software.

However, the result is that que es copyleft can be used for any kind of document. Strong and weak copyleft[ edit ] The strength of the copyleft governing a work is an expression of the extent that the copyleft provisions can be efficiently imposed on all kinds of derived works.

Only changes to the weak-copylefted software itself become subject to the copyleft provisions of such a license, not changes to the software that links to it.

This allows programs of any license to be compiled and linked against copylefted libraries such as glibc the GNU project 's implementation of the C standard libraryand then redistributed without any re-licensing required.

Instead, I explain that the communities involved have norms based of reciprocal behaviour and expect those working with their code to share with others the same freedom to innovate as they have received.

Releasing your code under one of the BSD licensesor some other lax, permissive license, is not doing wrong; the program is still free software, and still a contribution to our community. A programmer may want to contribute her changes to the community, but her employer may want to turn the changes into a proprietary software product.

When we explain to the employer that it is illegal to distribute the improved version except as free software, the employer usually decides to release que es copyleft as free software rather than throw it away.

To copyleft a program, we first state that it is copyrighted; then we add distribution terms, which are a legal instrument that gives everyone the rights to use, modify, and redistribute the program's code, or any program derived from it, but only if the distribution terms are unchanged.

Thus, the code and the freedoms become legally inseparable.
